10 Most Disturbing Sci-Fi Video Games You'll Ever Play

10. System Shock

Set in the far flung reaches of the year 2072, the original System Shock tells the story of a nameless hacker who, aboard the dark and oppressive Citadel Station, must hack a malevolent AI named Shodan as penance for previous hacking offences.

Whilst the rudimentary 1994 graphics and complex control scheme leave much to be desired by today's standards, they actually do a great job of conveying the dramatic tension and frequent sense of desperation the title strives for.

Wandering the twisting, labyrinthine corridors and claustrophobic anterooms of this cluttered station, the player will constantly hack into the system, acquiring new upgrades and piecing together the story.

The AI Shodan has taken over the station, reprogramming its robots to kill, and mutating the human crew into similarly nightmarish hybrid enemies.

Whilst the sequel System Shock 2 is definitely a better all-round game, and the upcoming remake of this debut title likely to far outshine the PC original, the emotionless, ghostly voice of the villainous Shodan echoing over the airwaves as the player fights off hordes of twisted enemies, ensures that System Shock remains a tense, stressful, and incredibly disturbing experience to this day.
